Expand description

A common interface to access the realizations for both TcpStream and UdpSocket

Required Methods§

source

fn connect(&mut self, timeout: Option<Duration>) -> CDnsResult<()>

Connects to the remote host.
If timeout is not set, the socket is initialized in non blocking mode and [PollFd] is created to use with poll(2).
If timeout is set, then the socket is initialized in blocking mode with timeout. Tht [PollFd] is not generated!

source

fn is_tcp(&self) -> bool

Tells if current instance is TcpStream if true, or UdpSocket if false

source

fn is_conncected(&self) -> bool

Tells if socket/stream is connected to remote host

source

fn get_fd(&self) -> Option<BorrowedFd<'_>>

Returns the raw fd of the socket.

source

fn get_remote_addr(&self) -> &SocketAddr

Returns the remote host Ip and port.

source

fn send(&mut self, sndbuf: &[u8]) -> CDnsResult<usize>

Sends data over wire.

source

fn recv(&mut self, rcvbuf: &mut [u8]) -> CDnsResult<usize>

Receives data transmitted from remote host. In nonblocking mode it should be called only after the event was polled In blocking mode it will block until received or timeout.
